Question

Which pair of substances might be involved in an oxidation-reduction reaction that would result in the formation of ions?
a. aluminum and oxygen
b. sulfur and oxygen
c. carbon and oxygen that would result?

Answer 1

To determine which substances might be involved in an oxidation-reduction reaction that would result in the formation of ions, set-up the balanced equation for each pair:

Aluminum and Oxygen

Al3+   + O2 ===> Al2O3

Sulfur and Oxygen

2S   + 5/2O2   ===> SO2 + SO3-2

Carbon and Oxygen 

C + O2  ===> CO2

Thus, only sulfur and oxygen produces ions in a Re-Dox reaction.
